Required properties:
- compatible: "samsung,s3c6400-hsotg" should be used for all currently
supported SoC,
- interrupts: specifier of interrupt signal of interrupt controller,
according to bindings of interrupt controller,
- clocks: contains an array of clock specifiers:
- first entry: OTG clock
- clock-names: contains array of clock names:
- first entry: must be "otg"
- vusb_d-supply: phandle to voltage regulator of digital section,
- vusb_a-supply: phandle to voltage regulator of analog section.
Example
-----
hsotg@12480000 {
compatible = "samsung,s3c6400-hsotg";
reg = <0x12480000 0x20000>;
interrupts = <0 71 0>;
clocks = <&clock 305>;
clock-names = "otg";
vusb_d-supply = <&vusb_reg>;
vusb_a-supply = <&vusbdac_reg>;
};
